FOUNTAIN-PEN.

BPECEIEIICATION forming part of Letters Patent No.337,838, dated March 16, 1886.

A pplication tiled Scptembu- 5, 18S5. Serial No. 176,237. (No model.)

To @ZZ whom 'may concern:

Beit known that I, JULiUs KLAUCKE, a subject of the King of Prussia, and a resident of Solingen, in the Empire of Germany, have invented a new and useful Improvement in Fountain-Pens; and I hereby declare the following to be a full and clear description thereof.

This invention relates to an oscillating ink reservoir or fountain, and to an inclined bridge placed therein for assistance in filling thesaid fountain.

The invention will be readily understood by reference to the accompanying drawings, of Whirh- Figure I' is a longitudinal sectional elevation of the improved pen. Fig. Il is a general plan of it. Figs. lll and IV are respectively longitudinal sectional elevations of the fountain or reservoir piece and of the socket or handle part. Figs. V and VI are respectively top plan views ofthe fountain part and of the socket or handle part of the said pen. Fig. VH is a perspective view of the handle.

This pen has a hollow handle, A, the front end of which receives a hollow socket-piece, B. The front end Yof the handlepiece A has an eXteriorly-projecting iiange or collar, a, the inside of which is chambered to receive the sliding collar-piece r, which, when it is shoved into its housing in the said collar a, holds the fountain part t united with its said handle, the other attaching parts ofthe said fountain, as hereinafter described, being in place.

The fountain or reservoir tis a hollow shell, closed at its back end and open onthe top side 0I its front end for nearly one-half its length. A transverse sloping diaphragm or bridge, s, is placed across the fountain-piece t near the rear end of its open front end part. When the fountainpiece t is in its working position in the pen-holder, the transverse diaphragm s closes the entire passage of the said compartmentt at that point, except as to the small central hole or aperture. Z, which permits the ink to dow through it to the nibs of the pen, as required in writing.

The fountain-piece t is madeto slide endwise into the socket-piece B, and has laterally projecting from its sides pins or trunnions 'i z', which slide into slots i', formed in the opposite sides of the front end of the socket-piece B, and on these pins or trunnions the said fountain or reservoir is allowed a slight oscillating movement in its inclosing shell, the socket-piece B. A longitudinal spring,f, attached to the fou ntai n --piece t near its rear end, and projecting laterally therefrom, is accommodated in the rear cud of the chamber B when the parts are assembled together, and habitually presses on the rear or inner end of the fountain-piece to throw that end of the said fountairrpiece down, though permitting it to rise up when the forward end of it is pressed down in the act of pressing down on the pen in writing, and in this manner a continued oscillating movement of the fountainpiece t on its tru nnions i is produced throughout the time of using the pen in writing.

The pen D is made to overlap and cover the open top of the front end of the fountainpiece t, and with the said fountain-piece the penis assembled to the handle by means of the sliding collar i'. An aperture, d, formed in the central top part of the pen,co1nes directly over the bridge or diaphragm swhen theparts are all assembled together in the position for filling the pen, as shown in Figs. I and Il.

ln filling the said fountain or reservoirt the pen is inserted iuto the ink, so as to submerge the tilliugaperture rl, and it is then inclined on its side, turning the pen until the ink vflows in and fills the cavity of the reservoir t above the bridge-wall or diaphragm s, which in the filling operation acts as aspoon or shovel.

Vhen writing, the pen spreads and turns upward, and the front end of the oscillating ink-holder follows the same direction, owing to its Working or oscillating on its supports or trunnions 'L' inand the action of the springfto habitually throw its said front end thus upwardly against the bottom side of the pen, and the ink can only flow to the point of the pen through the small split of the pen. Atoo great rush of ink is therefore avoided. The aperture l in the inclined bridge-wall or diaphragm permits the ink to flow into the opentopped front end of the reservoir t, and so readily gain access to the nibs of the pen. The small aperture o in the upper part ofthe holder allows for the movement of the air out of or into the upper part of the chamber t, as required in filling it or in Writing.

IOO

-stantly in contact lwith the inside of the pen,

and capable of following the up and down movements of the pen, substantially as shown and described.

2. In the ink-reservoir of a fountain-pen, a

`sloping transversebridge wall or diaphragm placed near the front end of said ink-reservoir, and provided with an aperture foralloW- ing the ink to feed through to the front end of the-said reservoir and thence through a suitable inlet to the pen in just such quantity and at such time as required for the use of the pen, substantially as shown and set forth.

8.' In a fountain-pen, an oscillating ink-reservoir placed within the handle of the pen 'and mounted on central trunnions supported in bearings in the handle, and having its lower end open-topped and placed against the inside of the pen, so as to readily deliver the ink thereto as the'pen and its adjacent reservoir oscillate or-vibrate up and down, as in the writing movement, which said movement of the pen causes the ink-reservoir to oscillate on its trunnions, substantially as described and set forth.

4. In a fountain-pen, a spring-actuated oscillating ink-reservoir placed within the penhandle and supported in suitable bearings therein, so as vto permit a longitudinal vertical oscillation which is imparted to it by the up and down movements of the pen inwriting, the front or lower end ot the reservoir being placed in Contact with the inside of the pen for this purpose, and for the ready delivery of the ink to the pen, substantially as shown and described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
